The actors didn’t need much cardio, because their functional training elevated their heart rates sufficiently. Each session was competitive, with a penalty-reward system tied to performance and results posted daily for all to see. Primitive tools-medicine balls, kettlebells, and rings-were used instead of machines. To support fight preparation, 300 training emphasized athleticism by combining compound movements, lifting, and throwing. The objective is genuine fitness, not the appearance of fitness…appearance is a consequence of fitness. They trained at the Gym Jones, invitation-only, fitness center in Utah.
300 training was done, while eating barely enough for recovery. Including the work they did with weapons training, the cast of 300 trained for 10-12 hours per day, five days a week, for four months.
